i worked on a mission on moho during the whole weekend..originally it was for lathye then seen the huge amount of dV i decided to try for moho. it consisted of: a) lander, one manned; refueler docked to lander in HKO, since i've been greedy on launching that stage; c) lifter with a three men capsule(1 empty seat :-D) docked to the lander in HKO; d) additional orange tank to refuel the lifter and, remaining attached, providing extra fuel and extra thrust on the aircraft (2 more nuclear engines); so far so good.. then i managed to end in moho orbit with not enough fuel to do anything else, let alone landing, so i designed an interplanetary refueling mission, which i managed to dock with something like 700-800 liquid fuel to fill a total amount of 2000 in the lifter and 1000 in the lander. i've done a second refueling mission with a different design, which came with even less fuel, but i should start the landing operation next weekend, also redocking the staged lander(pod and science junior) to properly revalue the dV the ship has..i think i'll need a third refuel even if i manage to save something from the lander before undocking its body.
